Brief description

Brook trout 1918Introductions of Salvelinus fontinalis (Mitchill, 1814) began in the nineteenth century, to more than 40 countries in temperate areas on all continents, including the southern hemisphere. The brook trout is considered a poor to moderate invader. Potential impacts include predation on various species of amphibians, zooplankton and other invertebrates as well as increases in primary productivity, alteration of nutrient cycles, and hybridization with native species. This species is competitive, with broad dietary breadth, has a fast growth rate, often lacks predators or parasites, and is moderately tolerant of abiotic conditions. Introductions may lead to replacement of native salmonids (e.g. brown trout, Salmo trutta) (CABI 2019).

Status and distribution in Luxembourg

Records of Salvelinus fontinalis Mitchill, 1814 in Luxembourg. Data source: Recorder-Lux, iNaturalist & GBIF, 2024-07-14.

Salvelinus fontinalis (Mitchill, 1814) was first mentioned in 1872 by Alphonse de la Fontaine, who wrote that the brook trout occasionally enters the Moselle from time to time (De la Fontaine 1872).

The species was introduced in Luxembourg in 1902 in Limbach (Lintgen), Rollingerbach and Berschbach (Feltgen 1902).

In 2005, a systematic inventory of Luxembourg rivers only showed isolated individuals in the Alzette. There is no indication of reproduction of the species in Luxembourg.

The distribution map is not complete because records still have to be entered into the Recorder-Lux database (MNHNL, iNaturalist & GBIF 2019).

Currently, 6 records of in Luxembourg are accessible through the MNHNL-mdata portal (MNHNL, iNaturalist & GBIF 2020).
